Federal obligations in aircraft engine and engine parts manufacturing (NAICS 336412)

Propulsion as its own manufacturing NAICS

NAICS 336412 covers establishments that manufacture aircraft engines and engine parts. On USAspending.gov the code tags contract awards classified that way: new engines, engine modules, and related parts production. Overhaul that is classified as manufacturing can also land here; depot maintenance classified as a services NAICS will not. The tag follows the award file, not a shop-floor tour.

Complete airframes are 336411. Other aircraft parts and auxiliary equipment are 336413. A fighter buy can put the airframe on one code and the engine on another. The $63.0 billion figure is only the engine-manufacturing slice. Readers who quote airframe totals as if they included engines, or the reverse, will misstate both tables.

Reading $63.0 billion in engine obligations

USAspending records obligations when agencies award or modify engine contracts. Production lots, spare engines, and parts orders all feed $62,979,247,344.26. This packet has no fiscal-year split and no outlay total. Engine programs are often multi-year; the obligation can sit on the award while deliveries continue.

Outlays are the payments that follow. Quote $63.0 billion as USAspending contract obligations coded to NAICS 336412, not as a propulsion budget and not as cash already spent.

14,885 awards, not 14,885 engines

The 14,885 award records include production lots, spare-engine orders, and modifications tagged 336412. The count is not a unit inventory of engines installed on federal aircraft. Compared with the residual aircraft-parts code, engine manufacturing typically shows fewer records and larger individual actions. Open the industry table for the actual mix.

An engine buy can be the largest line on an aircraft program and still be invisible on the airframe industry page. That is why 336412 exists. USAspending awards tagged aircraft engine and engine parts manufacturing show $62,979,247,344.26 in obligations on 14,885 records. Spare engines, production lots, and modules share the code when tagged this way. Residual airframe parts stay on 336413. Complete aircraft stay on 336411. Aviation support services stay on 488190. The 14,885 figure is not engines on wing. Cite USAspending, obligations, and propulsion. Keep outlays out. Keep fiscal years out; this packet has none. The industry page is the place to see how those 14,885 rows cluster.

What 336412 leaves out

Assistance awards often lack NAICS and are outside this total. Missile and space vehicle propulsion that is coded to 336414 or 336419 stays on those pages. Ground-vehicle engines are not this aircraft-engine line. Air-transportation support services (488190) are services, not engine manufacturing.

SpendingVault aggregates USAspending.gov contract data. The $62,979,247,344.26 total and the 14,885 award count can change after corrections. The live industry page is the table of record.

Using the aircraft-engine industry page

Open the AIRCRAFT ENGINE AND ENGINE PARTS MANUFACTURING industry page for the award list under the headline. Compare 336412 with 336411 and 336413 on All industries without combining the totals. Cite obligations, not outlays, and keep the 14,885 award count with the dollar figure.

Citing propulsion without the airframe

Cite $62,979,247,344.26 in USAspending obligations on 14,885 awards tagged NAICS 336412, aircraft engine and engine parts manufacturing. Say propulsion, not complete aircraft, not residual airframe parts. Those neighboring codes have their own pages and their own facts.

The 14,885 award count mixes production lots and spare-engine orders. It is not engines delivered. Outlays can lag on multi-year propulsion contracts. If overhaul was tagged as a services NAICS instead of manufacturing, those dollars will not appear in $63.0 billion. Check the industry table when tagging is the question.

Propulsion has its own factory code because engines are not airframes and not residual parts. The $62,979,247,344.26 total is awards tagged 336412. A spare-engine order, a production lot, and a module buy can share the 14,885 records. Overhaul classified as manufacturing can share them too; overhaul classified as aviation support services will not.

Readers who quote an aircraft-program cost from news coverage are not quoting this table. Program costs mix airframes, engines, support, and R&D. This page is the engine-manufacturing slice only. Cite USAspending obligations on 14,885 awards coded 336412. Do not convert the count into engines on wing. Do not invent a fiscal year.

Questions

How much is obligated on NAICS 336412 aircraft engines?

USAspending.gov contract awards coded NAICS 336412 show $62,979,247,344.26 in obligations across 14,885 awards. That total is obligations, not outlays, for aircraft engine and engine parts manufacturing. USAspending.gov records the amount as contract obligations, not outlays, on awards tagged NAICS 336412.

Are complete aircraft included in the engine total?

No. Complete aircraft manufacturing is NAICS 336411. This table’s $62,979,247,344.26 is engines and engine parts tagged 336412 only. The packet total is $62,979,247,344.26 across 14,885 awards; assistance awards often have no NAICS and stay outside the industry rollup.

Do 14,885 awards mean 14,885 engines delivered?

No. The 14,885 figure counts contract award records, including lots, spares, and modifications. It is not a unit count of engines. Treat the 14,885 figure as an award-record count, including orders and modifications, not as a physical inventory of products or sites.

Are other aircraft parts in 336412?

Other aircraft parts and auxiliary equipment use NAICS 336413. Engine manufacturing is 336412. Parts dollars tagged 336413 are not inside this engine total. This guide does not add a fiscal-year split. Quote the live industry page if you need the current award list under AIRCRAFT ENGINE AND ENGINE PARTS MANUFACTURING.
